STMicroelectronics has made an addition to its MEMS sensors portfolio aimed at advanced automation and the Industrial IIoT, and it comes with a 10-year product-longevity assurance. The IIS3DHHC is a three-axis accelerometer optimized for high measurement resolution and stability to ensure accuracy over time and temperature. It’s aimed at precision inclinometers in antenna-positioning mechanisms for communication systems, structural health monitoring (SHM) equipment for keeping buildings and bridges safe, and stabilizers or levelers for a wide variety of industrial platforms. Its long-term accuracy and robustness are also suitable for high-sensitivity tilt and security sensors, as well as image stabilization in high-end Digital Still Cameras (DSCs).
Other features of the IIS3DHHC sensor include an ultra-low noise of 45μg/√Hz and a full-scale range of ±2.5g. It integrates analog-digital conversion, as well as digital circuitry including FIFO data storage and interrupt control. The IIS3DHHC is in production now, in a 16-lead, 5- by 5- by 1.7-mm ceramic LGA package, priced from $4.50 for orders of 1000 pieces.
